To aZZ whom it may concern:

Be it known that I, PnEsTo BnLvIN, a citizen of the United States, residing at Richmond, in the county of Henrico and State of Virginia, have invented certain new and useful In'iprovements in Heating and Ventilating Apparatus, of which the following is a specification;

This invention relates to improvements in heating and ventilating apparatus and has as one of its objects to'provide an apparatus of the class referred to especially adapted for the heating and ventilating of school rooms and similar places of assembly,'where economy'in space is desirable and where it is necessary to provide a constant supply of fresh air to the room at a suitable temperature and constantly remove the foul air.

The apparatus embodying the invention includes a.v heating unit, such for example as a. coal stove, although any other kind of fuel may be consumed by selecting an appropriate'unit, and a drum which substantially encloses the heating unit and in connection with whichthere are provided certain pipesv and conduits for the purposes of ventilation and carrying 01f the'foul air, as will be presently explained, and one of the objects of the invention is to so construct the drum that no live coals or ashes from the heating unit or stove can fall to the floor within the drum to cause fire, and likewise so construct the drum that free access may be had to the doors of the stove and so that a part of the stovewillbe exposed'in a manner to permit of pupils attending the school, drying their clothing and Warming their feet.

Another object of. the invention is to so construct the apparatus that the heat from the stove will be utilized to advantage in not only delivering to the room a continuous supply of fresh air, but also to continuously remove, from the vicinity of the floor, the foul or vitiated air without, however, creating any annoying drafts in the room.

In the accompanying drawings:

Figure 1 is a view partly in elevation and partly in vertical section illustrating the appartaus embodying the invention installed.

Figure 2 is a front elevation of the heating unit and drum of the apparatus.

Figure 3 is a horizontal sectional view taken substantially on the line 33 of Figure 1, looking in the direction indicated by the arrows. V

The heating unit of the apparatus is indicated in general'by the numeral 1 and comprises any appropriate type of stove such, for example, as the upright heating stove 2 shown in the drawings and which stove is provided with the usual fire-box door 3- and ash-pit door 4, the stove being supported with its base 5 in somewhat elevated position above the floor of the room in which the appa'ratusis installed, by the usual legs 6. The floorof the room, is indicated by the numeral 7 in Figure 1 of the drawings and, in. accordance with the prin ciples of the invention, an opening 8 is formed in the floor directly beneath the stove, and a grating 9. is arranged within the opening. The numeral 10 indicates a fresh aid conduit whichimay be of wood, metal, or anyother material found suitable forthe purpose and maybe of any desired construction and dimensions,- this conduit being closed at its inner end and extending. beneath the floor 7 with its said inner end in communication with the opening 8. The other end of the conduit is. placed in communication with an opening 11 formed in the wall 12 of the building in which the apparatus is installed, and a screen 13 is preferably positioned upon the outer side of the wall 12 to extend over the outer end of the opening 11 and prevent the entrance of vermin into the conduit 10.

The heating unit 1, is enclosed within a drum 14 which is preferably of sheet metal and substantially cylindrical, being of a diameter greater than the diameter of the stove and having an opening 15 formed in its wall and defined by side plates 16 which extend inwardly from the wall of the drum and have their free vertical margins cut away to conform to the contour of the stove proper so that their said margins will contact the body at opposite sides of the front thereof. A plate 17 extends inwardly from the wall of the drum at the upper side of the opening in the drum and the inner edge portion of this plate extends beneath the usual rim or flange 18 at the top of the stove. A similar plate 19 extends inwardly from the wall of the drum at the lower side of the opening-and at its inner edge projects beneath the rim of the base 5 of the stove. In this manner, the front of the stove is sullieiimily ex tuiised in the opening in the il'illll? oi" lhe drum to permit oi ili'nll henelit lining); (lei-lived from the heat thrown oil? ilii'eel'ly from the stove, for the purpose oi peiiuiitl'iiur pupils to \i'lllflll their feet and (iljf their oloihingg' in ineleuieut Weather, the lliil lwl portion ol the stove, however, heing sui'i'ouni'led in the drum, end the plates; 16, ll" and. 19 constituting; hnilles to preventesenpiia oi: hoot from the interior of the drum. The ih-uin iiv Slllifiblf secured to the floor T us iiulieaited h the numeral 20 and is open at its top.

The numeral, ii. indienles :i stove pipe n'liieh leniils i'ioiu the top ol the alone 52, in. the usunl ninnnei', and is provided with the usual dnn'ipei' This pipe is connected h nu elhon' 9.3 with :i pipe illl: which ontends horizontally within the upper side oi. n pi'ecliei'uliily eylindi'ienl shell which is filled :it one end into on. opening 96 iloi-ined in the null 12 and coiniuunientino with the line or chimney 2?, the end of the pipe 24 pie'loi'uhly tein'iinnl'in e' suhsltnniisill} flush with the said end oi. the shell. Tl'ie other end of the shell. is closed as indicated h the numeral 25%, except lei on opening; 29 through which the pipe 524: is introduced. The numeral 30 indicates a foul nii: oonduit 01 pipe Whieln at its upper end, is in C0111- nninieelion with the lower side of the shell udjneent the closed end Q8 thereofi the lower portion oi the conduit 30 e. sendingi'lon'uunrdly into the drum 14.- in Ten? oi the stove 2 end reletivelv close to the said stove so as to he heated l'hei'ehy. A damper Ill is arranged in the conduit 39, and the ('fillllllli? is provided at its lower end with an intake ln'unih 39, extending); zit suhstuntinlly right entries i'hei'eiliioni end through an o 'ieuiug 3? formed in the all oi the drum ll. near the hottoni thereof.

It will likewise he evident than; inesn'iuoh es the lower portion ol the liEOlll'Zlll conducting pipe or eondnit is loonleil Within the drum 14, ll: will he subjected to n high degree oi. temp ri'eiui'e andw therefore, the upward mssnge oi l'oul air will he g'i'eutly facilitated and 'ihe i'oou'i more thoroughly ventilated. It "will else he tlfound that. lTJElSll'lllCll as the heati up unit is substantially onolosed Within the drum, :in updraft Will he created Within the drum serving;- to draw in fresh :iii." through the .seveon. l3 and opening 11 and by Way of the conduit 10, to he heated in the drum and delivered through the open top thereof and i nlo the room. Fllll'llGlll'lOlG, by providing" the drum with the bullies or shields 16, 17 and 19, no hot cools or ashes can :l'nll to the floor oi? the room Within the confines oi? the drum. At the some time, a portion o i the surface of the heating unit is directly exposed to the atmosphere of the room so that pupils standing); in :l'i'ont of the appin'w tus may worm their feet and dry their ehithine; in. inclement Weather.

Having thus described the invention, What I claim is:

In a structure of the character described. :1. stove including. a body having fire-hex and ash pit doors and menus to support the body in spaced relation to o floor, a, drum disposed about said stove in. spaced relation thereto and open at its top and of :1 height to extend above the stove. said drum having on opening; formed therein of a size to ex nose the portion of the stove provided with the fire-hex and ash pit doors. plates extending; inwardly froin the sides of said opening in converging relation to each other and having close lilting engagementn'ith. the stove, and plates extending inwardly from the upper and lower ends of said opening end respectively having close fitting: engagement with the stove above the fire-box door and below the ash pit door, the side plates constituting i'eileeliors for directing heat ontu'nrdly from the stove.

in testimony whereof I allix mysignoture.
